Set up "correct", but no sound, vu meters don't move

[Buddyhu]

Direct monitoring was off...just turned it on to assure that input was reaching the Focusrite. It turns out that a friend helped me to figure this out. It was related to Apple security: I had to go into the System Preferences - Security and Privacy - Privacy - Microphone and check a box that enables JamKazam to use the "Microphone". Was able to join a jam yesterday until the JamKazam server crashed.
